UNITED STATES EMIL KOLL, OF CINCINNATI, OHIO.

PIANO-FLANGE.

Application filed February 13, 1919.

T 0 all whom it may concern Be it known that I, EMIL KoLL, a citizen of the United States, residing in Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in Piano-Flanges, of which the following is a specification. 7

An object of my invention is to produce a piano hammer which is more easily dismantled and removed from the flange rail than piano hammers heretofore constructed and known to me.

A further object is to produce a piano hammer in which improved means are provided for adjusting andeliminating excessive wear.

These and other objects are attained in the piano hammer described in the follow ing specification and illustrated in the accompanying drawing in which Figure 1 is a side elevation of a piano hammer embodying my invention.

Fig. 2 is a front view of my improved piano hammer.

Fig. 3 is a front view of the hammer mounting flange embodying a feature of my invention.

Fig. l is a side view of the flange shown in Fig. 3.

Fig. 5 is a rear view of the flange shown in Figs. 3 and 4.

My invention relates particularly to the mounting means of piano hammers, and consists of a hammer flange 6 which is secured to the flange rail 7 by a screw 8, and a flange clip 9 which secures the hammer butt 10 to the flange by means of its clamp ing action upon the center pin 11.

At its lower end the flange 6 is forked to permit the screw 8 to occupy the space be tween the branches thereof and thus afford Above the Specification of Letters Patent.

Patented Sept. 21, 1920.

Serial No. 276,705.

fork a groove 12 is formed, in which the end 13 of the flange clip is located, and at the upper end of the flange and flange clip are grooves 14 and 15 which permit of the clamping therein of the center pin 11 when screw 8 is tightened.

In assembling my improvedconstruction the flange is located to the rear, with the flange clip in front. This brings the screw 16 in front and in accessible position without having to remove the flange in order to get at the screw 16, as is customary in flange construction now in use.

Another feature of my invention is that the groove 12 cooperates with the inturned end 13 of the clip to preserve perfect alinement of the upper end of the flange and the clip so that there can be no binding of the upper ends of the flange and clip between the sides 17 and 18 of the hammer butt 10.

Having thus described my invention what I claim is A piano flange having parallel front and back surfaces and a slot therein adapting the flange to be adjustably secured to a piano flange rail, said flange having a groove therein, a flange clip having an inturned end adapted to occupy the groove, a screw entering the flange rail from the front and occupying the slot, and a second screw passing through the flange clip from the front and entering the flange, said flange and clip having registering grooves on their contacting surfaces to receive the center pin of the butt.

In witness whereof I aflix my signature in the presence of two witnesses.
